Letters Patent No. 98,197, dated December 21, 1869.

IMPRovED PAVING-BLOCK Qrv-- The Schedule'refen'ed to in these Letters Patent and making part of thelam.

To alla-hom it may concer-n Be it known that I, REUBEN SALER, of Madison, in the county of New Haven, and State of Connecticut, have invented a new Improvement in Paving- `Blocks; and I do hereby declare the following, when taken in connection with the accompanying drawing, and t-he letters of referencemarked thereon, to he a full, clear, and exact description of the same, and

which 'said drawing constitutes -part of this speeiiication, and represents a perspective view of one of the blocks, preparatory to coating.4

This invention relates totali improvement in the construction ot blocks for paving, as a substitute for brick or stone, the object 'being to construct a wood form, which may be coated with any ofthe known compositions for concrete or asphalt-um pavements, and consists in the formation of blocks from ,two thicknesses ot' wood, the grain of one running transverse to the grain of the other, and the upper surface perforated or indented, seas to forni numerous cavities, into which the coating-material is pressed, so that the coating-inaterial on the surface will not flake from the wood.

A is the under part of the block, and B, the upper vpart, formed from any suitable wood, the grain of one bldck running transverse to the grain of the other, as seen in the drawing, and the two parts firmly secured together, whereby the warping or twisting'of the blocks is wholly avoided.

In the upper surface I form numerous cavities or indentations, as denoted in the drawing, and this I do l by boring into the surface a short distance, which completes thc block, preparatory to coating.

It should be observed that the Wood must be thoroughly dried before-it is coated. l

'lhe material used for coating may be any of the known compositions, as cement, asphalt-um, and the like, and this is applied over all the surfaces, so as to completely cover the block, the material being pressed upon the block, so that the various blocks are, tbrconvenience, of the same sized The material rum ninginto the cavities of the surfaces of the blocks, causes itto adhere more strongly to the suiface, aud prevents its crac-king or flaking ti'om the surface.

The blocks, after being coated, and the coating hardened, are made inthe usual manner for laying stone `0r other tile.-

I claim, as my invention- The paving-blocks herein described, consisting of two' thicknesses of wood, Combined as described, the upper surface indented or perforated, and Coated, substantially in the manner herein set forth. .REUBEN SHALER.'
